How to go from a Technician role to a Engineer

I'm currently a Operational Technician at Bosch. I pretty much troubleshoot the machines if they go down and keep the line running. Examples are rejected parts, replacing broken tools, hard checking parts, AM's/PM's, HMI interface issues, reworking parts, clean sensors, change over parts and components, etc. If there are bigger problems, I hand it over to Maintenance and I've learned how to fix some of their common problems.

Engineers obviously make more money. How do I get to that point?

Sidenote: I also kind of regret getting a degree in Mechatronics because it's too broad. I wish I just choose a single engineering group like Robotics, Mechanical, Electronics, etc.
